FAQs
EBMX1B-W035 uses a Size 1, copper-free aluminum enclosure with a clamped cover and three-pole construction, designed to fit standard hazardous-location panels. Its 22.11 in length, 12.86 in height, and 15.98 in width provide a predictable footprint, while the 80 lb weight informs handling and rigging considerations. This makes retrofits and new installations straightforward in environments requiring Class I Division 1/2 and Zone 1/2 compliance.
The EBMX1B-W035 is rated for Class I Division 1 and Zone 1, with additional classifications for Division 2 and Zone 2, along with Class II and III locations. It carries NEC/CEC standards and UL certifications for hazardous environments, and its NEMA ratings of 3R 4X 7 9 reinforce protection against moisture, corrosion, and impact. This combination ensures code-compliant installations in demanding industrial settings.
A 600 VAC nominal rating supports direct integration with common industrial distribution schemes, while the 35 AIC interrupt rating ensures rapid arc quenching under fault conditions. Together they minimize arc damage and equipment downtime, enabling safer switching of motors and non-linear loads in hazardous areas. This combination is essential for protecting both personnel and critical process equipment in challenging environments.
Clamped enclosure covers simplify field assembly and maintenance, reducing the number of fasteners and alignment steps during installation. The clamped design also supports reliable sealing in hazardous locations, helping maintain enclosure integrity against dust and moisture. For technicians, this translates into faster commissioning and easier part replacement without compromising safety.
The copper-free aluminum enclosure reduces weight and corrosion concerns, while the availability of replacement parts lists and SP3D design packages from Eaton supports proactive maintenance and design optimization. The combination of robust certification, durable materials, and accessible support resources lowers total cost of ownership by decreasing downtime, simplifying regulatory compliance, and extending service intervals in demanding plants.
